Abstract: Based on the assumption of elastic support of soil nail, the expressions for calculating the real-time dynamic change of soil nail force and the seismic displacement of slope are derived by using the pseudo-static limit equilibrium method, considering the influence of real-time dynamic slip during earthquake. An improved method is proposed for calculating the seismic displacement of soil nailing slope under earthquake. The results of an example analysis show that the calculated time history curve of the slope horizontal displacement with and without considering the real time dynamic change of soil nail force are basically consistent. All results present a trend of step-wise increase, but the horizontal slope displacement calculated by the improved method is smaller, and the differences between results from two methods decrease gradually with the improvement of the overall stability of the slope. In the end, the rationality of the improved method is verified by comparing with the experimental data of shaking table test for a soil nailing slope.
